My web site, pictures 10 and 11 show 1 of the little buggers. Had someone just Id'd them for me, as these guys and I'm a little concerned. I have spotted 6 of them at this point, one was out 1 time and it had six legs and was about 2" long. Most of them don't come out of the rocks, all I see are little legs sticking out.

By looking at the picture here I would guess this guy is the same strain. Anyone know how big they get?
I had a green bristle star that got really huge and was eating my fish. Really don't need that or eating my corals.

They are micro stars and will never be big, a big one would be 3/4" from tip of one leg across to another. They are harmless.

From what I heard, only the green stars are fish predators.

Well thank you VERY much.. Any addition to the clean up crew is a good thing. I'm thrilled to hear they're harmless as I really like watching them.
Take care

That's not true, my mother had a chocolate chip that ate her fish. And from the research I've found on the web, stars that are shaped like the chocolate chip can be aggressivve.

Well, chocolate chip star isn't ophiouroid but rather a true sea star(asteroids) so it is true that of all the ophiouroids the green brittle star( Ophiarachna incrassata) is probably the most dangerous. Or should I say the most opportunistic feeder than the rest of them.
